Implementation of the ROD Crate DAQ Software for the ATLAS Tile Calorimeter and a Search for a MSSM Higgs Boson decaying into Tau pairs
2010
The ATLAS experiment of the LHC at CERN started its operation in 2009. The ROD Crate DAQ (RCD) as a part of the Trigger and Data Acquisition system (TDAQ) is responsible for the operation of the sub-‐detector specific hardware at the level of the back-‐end electronics crates. The RCD for the Tile Calorimeter is fully implemented. In first place, the specific Tile hardware and software is described in the configuration database. In second place, the various plug-‐ins for the RCD that make use of sophisticated programming techniques are characterized. The RCD performance can be evaluated in terms of global DAQ efficiency, which is over 94% for the considered period in 2010 and in terms of …
Sterile neutrinos as dark matter candidates
2021
In these brief lecture notes, we introduce sterile neutrinos as dark matter candidates. We discuss in particular their production via oscillations, their radiative decay, as well as possible observational signatures and constraints.
Search for the neutral Higgs bosons of the Minimal Supersymmetric Standard Model in $pp$ collisions at $\sqrt{s}=7$ TeV with the ATLAS detector
2013
A search for neutral Higgs bosons of the Minimal Supersymmetric Standard Model (MSSM) is reported. The analysis is based on a sample of proton-proton collisions at a centre-of-mass energy of 7 TeV recorded with the ATLAS detector at the Large Hadron Collider. The data were recorded in 2011 and correspond to an integrated luminosity of 4.7 fb[superscript −1] to 4.8 fb[superscript −1]. Higgs boson decays into oppositely-charged muon or τ lepton pairs are considered for final states requiring either the presence or absence of b-jets. No statistically significant excess over the expected background is observed and exclusion limits at the 95% confidence level are derived. The exclusion limits ar…

Development of low-diffusion techniques for a high pressure xenon electroluminescent TPC

El neutrino es una partícula que ha despertado un gran interés en las últimas décadas. Su existencia fue conjeturada por W. Pauli en 1930 para explicar el espectro continuo de la desintegración beta. El descubrimiento inequívoco de la oscilación de neutrinos en 1998 demostró que los neutrinos tienen una masa que no desaparece. Por lo tanto, es necesario acomodar un neutrino masivo en la teoría expandiendo el Modelo Estándar y eso se puede hacer suponiendo que el neutrino es una partícula de Majorana, que se define como un fermión que es su propia antipartícula. El mecanismo que da su masa a un neutrino Majorana podría explicar la leptogénesis y parte de la asimetría materia-antimateria obse…

ATLAS data quality operations and performance for 2015-2018 data-taking
2020
The ATLAS detector at the Large Hadron Collider reads out particle collision data from over 100 million electronic channels at a rate of approximately 100 kHz, with a recording rate for physics events of approximately 1 kHz. Before being certified for physics analysis at computer centres worldwide, the data must be scrutinised to ensure they are clean from any hardware or software related issues that may compromise their integrity. Prompt identification of these issues permits fast action to investigate, correct and potentially prevent future such problems that could render the data unusable. This is achieved through the monitoring of detector-level quantities and reconstructed collision ev…
